Fortunella obovata. Oh my. The Fukushu kumquat, also known as Changshou, is our new favorite citrus fruit by far. The round 2" fruit packs a punch without puckering the mouth and the intense citrus flavor from one Fukushu kumquat will carry you through the day. It's perfect for eating on its own, slicing into fish or poultry dishes, and sprinkling over salads. We will choose the Fukushu kumquat over chocolate truffles any day. The tree is highly ornamental to boot, with its unique rounded leaves and spreading, thornless form. Flowers in summer and fruits in winter. As of May 2017 the trees are small, about 2' tall, a few fruit. Grown on dwarfing rootstock in 5 gal containers. Shipped in 3' x 1' x 1' braced boxes. ONE PER CUSTOMER.
